ciencywill prevail with a minimum con sumption ot; 1 In addition I provide means for insuring perfect mix ng and combustion'fiftheair and as thereby eliminatingiodorsj-orinoxious' unics.

"Vain; aware that heat ng devices of a somewhat similar nature and intention have been patented but my invention resides primarily in roviding'an upper disposed compartment or collecting the products of combustion'before'the'y areiallowed to enter the room in which compartment all carbon or other foreign matter given ofiby the ignited air and gas, 'or drawn into the heater by the naturaldraft, will be deposited, which feature is of practical advantage and will be appreciated by th se skilled in the art.

The comparatively few parts entering 80 into the construction of my heater insures cheapne'ssof manufacture, both as to ma- 4 terial and laborffor assembling, at the same time providing themaximum ofradiating area. a 1 a Inthe accompanying drawing is shown one embodiment of'my invention, which I desire it understood is merely illustrative,v

the same being subject to such alteration and amendment as future practice and experi- 40 menting may dictate.

Constructively my device, as disclosed in the accompanying drawing, involves a suitable base. portion 1, which I intend constructing out of some bright reflecting ma- 4 terial, such as copper, brass, or nickel, said base being of suitable configuration, and supported on-legs 2. Passing up through the said base, and extending to a predetermined height thereabove, is a hollow column or'riser 3 which acts as a conducting means for the fuel gas supplied by a pipe 4 and in addition supports a. suitable burner 5 adjacent to its upper extremity. Adequately supported by the said column above the burner is an outwardly flared hollow coneshaped member 6, which performs the func- Specification of Letters Patent.

tion of a deflecting means, while above this latter described portion, and suitably spaced-apart therefrom, is a second hollow cone-shaped member 7 of somewhat less diameter than the said member 6, also supported by the column 3. The walls of this said element 7 are provided with a plurality suitable sized apertures 8, and the outer rim is provided with a flange 9 in order to 55 insure an engaging or fastening means in congunction with the surrounding dome 10, a to whichjsaid member 7 is secured by clips 11 or any other adequate means. The apex ofsald dome is here shown as being slightly 70. v raised above the main body portion thereby forming a hollow cap or recess of predetermined diameter, which said recess, taken in conjunction with the s'ace formed by the inner walls of the mem er-7, 'formsan upper central compartment 12. Said cap or apex of the dome isprovided with a lurality of apertures 13 to insure a nature draft and egress of the heated air from the said compartment. The vertically. disposed side so walls of said dome which may be of solid formation or grilled as shown; preferably extend to a point'belowthe-horizontal line of the burner in order {tof'encompass and 5 partially conceal said burner coupled with their function as radiating orti'ons of the heater, said walls being su j'ected to the heat from the burner. t will be observed thatthe under side of said dprne is open on all sides to the atmosphere in order that the an ignited gas is assured a suficiency of air for proper combustion and in addition that the heater will be supplied with a proper amount of fresh air to be heated and expelled into the room. as

The flame will be deflected outward toward the side walls of the dome by the memher 6 the heat or products of combustion passing upward through the space 14, thence into the communicating space 15 between the two members 6 and 7, then into the compartment 12 through the apertures 8, in which compartment ,the carbon or other foreign jacent to the upper section or apex of the dome between the entrance and exit apertures, which baflle tends to aid in the deposit of carbon or other elements held in suspen-' sion in the fuel gas and air.

It will be apparent that my form of heater affords the maximum of radiating area in that the dome and deflecting member will give off heat in all directions, due to the open formation of the device, and in addition the base portion 1 will likewise become heated and give off its proportion of radiation.

The clip members 11 carried by the dome, cooperating with the roof of said dome and flanged upper portion of the inner cone, affords a ready means for removably looking said dome in position, from whence it can be quickly disengaged should it be necessary to uncover the inner compartment for cleaning purposes.

WVhat I claim as my invention is 1. A heating appliance having a suitable base; a hollow column rising above the base, said column acting as a conducting means for the fuel supply; a burner carried by the column in communication wit-h the fuel supply means; a hollow inverted cone-shaped deflecting member above the burner; a sec ond hollow inverted cone-shaped member interior of and spaced-apartfrom the said defleeting member, the walls of which are perforated; a dome supported by the inner disposed cone, the apex of said dome being perforated and forming a hollow cap portion which, taken in conjunction with the said inner cone, forms an inner compartment; and means carried by the dome for removably securing said dome in position.

2. A heating appliance having a suitable base; a hollow column rising above the base, said column acting as a conducting means for the fuel supply; a burner carried by the column in communication with the fuel supply means; a hollow inverted cone-shaped deflecting member above the burner; a second hollow inverted cone-shaped member interior of and spaced-apart from the said deflecting member, the walls of which are perforated; an inclosing dome supported by the inner disposed cone, the apex of said dome being perforated and forming a hollow cap portion, which, taken in conjunction with the said inner cone, forms an inner compartment; and clip members carried by the dome for removably locking said dome to the said inner cone.

3. A heating appliance having a suitable base; a hollow column rising above the base, said column acting as a conducting means for the fuel supply; a burner carried by the column in communication with the fuel supply means; a hollow inverted cone-shaped deflecting member above the burner; a second hollow inverted cone-shaped member interior of and spaced-apart from the said deflecting member, having perforated walls column in communication with the fuel supported by the inner disposed cone, the apex of said dome being perforated and forming a hollow cap portion, which, taken in con.- junction with the said inner cone, forms an inner compartment; clip members carried by the dome for engagement with the flanged portion of the inner cone for removably locking said dome in position; and a screen interior of the said inner compartment removably held in position by the said clips.

In testimonywhereof I aflix my signature in the presence of two witnesses.
